What is the definition for Genotype and Phenotype ratios?
The genotype is the actual code for a trait. Hidden on the chromosome we can never actually see the alleles controlling the trait unless we sequence the DNA. The phenotype is the result of at least two alleles expressing a visible or measur... Read More »

What is the ratio for these genotypes and phenotypes?
The genotype ratio is 1/4 RR : 2/4 Rr : 1/4 rr or just 1 RR : 2 Rr : 1 rr or 1:2:1 The phenotpic ratio is 3 R_ : 1 rr or 3:1 Source(s): Forty years teaching Genetics Read More »

In case 1, you are crossing 2 tall heterozygotes Tt x Tt. Each parent can produce either T or t gametes which will combine independently to give: TT Tt tT tt. Genotypic ratios are therefore 1:2:1 I am assuming T is dominant, so both TT and ...

Let A be the dominant allele a be the recessive allele heterozygous dodo is Aa and the homozygous recessive dodo is aa the resulting cross is Aa x aa genotypic ratio will be 50% Aa and 50% aa or 1/2Aa:1/2aa.. It can also be 1:1 phenotypic r...

Each pink flower will be Rr (one red gene, one white). GENOTYPE - 25% RR, 50% Rr, 25% rr. So a ratio of 1:2:1. PHENOTYPE - 25% red, 50% pink, 25% white. So again, a ratio of 1:2:1.

Let's start at the beginning. A genotype is the allele combination for a specific trait. For example, the trait you inherit from your parents for tallness; the genotype may be Tt. The phenotype is the physical appearance. For example, long ...
